Inside Grand Seiko: The Evolution Of The Spring Drive Movement

In the second installment of our three-part series in partnership with Grand Seiko, we go in-depth on the history and development of Spring Drive.

First Look – The Singer Heritage Collection Chronograph with Restored Valjoux Movement

Singer (understand Singer Vehicle Design) first made a name for itself with its bespoke restorations of the Porsche 911, and in recent years, the California-based brand has also been turning heads in watchmaking with its Track 1 chronograph – known for its unconventional layouts and innovative AgenGraphe movements developed by Agenhor, without forgetting the Divetrack, […]

Hands-on – The Tudor Black Bay 58 Burgundy, now with METAS Movement and More Updates

Of all the new releases from Tudor at this year’s Watches and Wonders, the standout piece was undoubtedly the evolution of the Black Bay 58 line, now presented in a striking all-burgundy design, with both the dial and bezel dressed in the deep red tone. While the dial colour holds historical significance, the real game-changer […]

Hands-on – The Nicolas Delaloye Renaissance Tantalum 39mm and Its Superb Handmade Movement

Despite being an experienced watchmaker in his 50s, Nicolas Delaloye remains one of the discreet names in the independent watchmaking scene. But there are good reasons for that. This AHCI member just regained his independence and re-started making watches a few months ago, after a long period serving as a watchmaker-restorer at the Patek Philippe […]

Cartier Revisits the Tank à Guichets with an In-House Movement

One of the most distinctive versions of Cartier’s signature rectangular watch, the Tank à Guichets has been revived as part of the Privé collection, joining watches like the Tortue Monopoussoir and Tank Cintree. The last time Cartier had such a model in its catalogue was exactly 20 years ago with the Collection Privée Cartier Paris (CPCP) iteration. Sporting a crown at 12 o’clock like some historical examples of the model, the Tank à Guichets indicates the time in twin apertures, with jumping hours at 12 o’clock and minutes at six. Measuring a slim 6 mm in height, the Tank à Guichets (or “Tank with Windows”) is powered by a new in-house movement, the cal. 9755 MC. Notably, it will be a regular production model in yellow or rose gold, as well as platinum, plus an asymmetrical or “oblique” model that is limited to 200 pieces. The regular production models (left), and limited edition Initial thoughts The Tank à Guichets was always one of my favourite iterations of the Tank, and the popularity of the preceding version made it almost inevitable that Cartier would revive the design. The new Tank à Guichets is subtly different from the CPCP version, most notably in its slim profile, but still looks and feels correct. The finishing on the case is excellent, particularly on the polished bevels that frame the apertures. The movement, on the other hand, is concealed behind a solid back but is industrial in finish and style. That said, it is an integrated calibre ...

Introducing: The New Panerai Luminor Marina Collection, With New Movement And New Measurements

A slightly slimmer big watch with some even bigger upgrades.

First Look – The new Tank Louis Cartier with Automatic Movement

Louis Cartier’s Tank watch, introduced in 1917, marked a before and after in men’s wristwatches. Breaking with the taste for ornately decorated cases, the Tank Normale’s geometric case, inspired by an aerial view of armoured Renault tanks deployed in WW1, was a precursor of the clean minimalist lines of Art Deco. Thanks to its well-executed […]

The Rolex Land-Dweller is Here: We Got a Watchmaker’s Perspective on the Crown’s New Dynapulse Movement Technology

In recent days, much of the watch internet has been abuzz with the apparent news of a new Rolex collection with the somewhat hard to believe name of Land-Dweller. Leaked images of the Crown’s new watch began to emerge in the days leading up to this year’s Watches & Wonders, and, as you’d expect from the internet, debate ensued. The shots purported to capture a Datejust-adjacent design with sharper lines and, perhaps, an integrated bracelet. The official Rolex teaser for Watches & Wonders on Instagram seemed to confirm many of the details that had already been guessed, and then a very Daniel Craig at the Olympics style image of Roger Federer wearing the watch hit social media via the tennis star’s (and Rolex ambassador’s) Instagram account. It appeared to everyone at this point that the Land-Dweller was real – we only had to wait for the details.  Rolex has made those details public as of today, with the announcement of the new Land-Dweller collection. This is much more, though, than Rolex jumping on the integrated bracelet sports watch bandwagon (although, it is that, at least a little bit). The Land-Dweller is also an important moment for Rolex as a movement maker, as it introduces their new, patented, direct impulse escapament which goes by the trade name Dynapulse. It uses dual silicon wheels and introduces us to Rolex caliber 7135. More on that caliber in a moment, but first, the broad strokes of the Land-Dweller collection. The new collection features a f...

First Look – The Handsome Montblanc 1858 Geosphere Annual Calendar with Minerva Movement

Montblanc‘s appreciation for Minerva‘s heritage drives its evolution as a watchmaker. The brand embraces Minerva’s time-honoured craftsmanship and savoir-faire by celebrating traditional techniques while exploring the possibilities of modern horology. This commitment is again evident in the newly unveiled 1858 Geosphere Annual Calendar, a timepiece poised to become a standout addition to Montblanc’s collection with […]

Zenith Reimagines Its Caliber 135 For The 21st Century

The year 2025 marks 160 years since the founding of Zenith in Le Locle, Switzerland, back in 1865. As watchmaking brands are wont to do, Zenith is commemorating this milestone by putting forward a watch for the occasion that’s representative of its storied history, as well as its own contemporary identity. Now, as Watches & Wonders 2025 kicks off, we are clear on how the brand aims to celebrate the occasion, and its chosen vehicle is a new collection inspired by Zenith’s own founder, complete with an update on its storied Caliber 135, which breathes fresh life into an old favorite movement. These are the conditions in which the rising star of the G.F.J. collection joins Zenith’s constellation. At the tail end of the 19th century, the mounting competition within the watch industry brought about a new standard of gauging the accuracy of movements, and watchmakers began employing observatory trials to signal to customers that their products were as accurate as possible. This was also at a time in which highly accurate timepieces were necessary for successful marine navigation. Before the COSC certification standards that are so rigidly defined today were coded, individual movements would be sent to observatories, where they would undergo testing procedures, as well as competitions for chronometry prices. Zenith details that it had been routinely entering chronometry trials as early as 1897. And, because a bit of healthy bragging is appropriate with brag-worthy achieveme...

Horage Debuts the K3, an All New Antimagnetic Caliber, and the Decaflux, an Affordable Everyday Sports Watch

The independent brand Horage has produced some of the most genuinely interesting watches of the last several years. They’re a bit of a tough brand to pin down. Depending on how you discover them, you could mistake them for a brand obsessed with links between watches and photography, or one of a handful of small indies doing interesting things with tourbillons and other watchmaking tech for quite a bit less money than you’d typically expect. But the thing that links all of their products together is a desire to come up with creative solutions to long standing watchmaking problems and to do so in a way that doesn’t leave anyone out of the experience. Accessibility and approachability are as vital to Horage as their love-it-or-hate-it design language, often embracing an ultra contemporary sensibility.  Two new announcements from Horage over the last week or so perfectly illustrate their commitment to quietly pushing horological boundaries. First came the introduction of their new K3 movement. Over the last several years, most of Horage’s big movement developments have come with some high end features and represent big swings for the brand. The tourbillon, of course, is arguably the centerpiece, but they’ve also introduced a micro-rotor caliber as well as a fascinating tool that allows for the periodic electronic regulating of that very movement. But the K3 is a comparatively simple idea, a high quality movement made from advanced materials at a relatively low cost....

First Look – The Louis Vuitton x Kari Voutilainen LVKV-02 GMR 6, a Tantalum Escale with Superb Kari Movement

As we’ve seen with recent initiatives, things are moving fast at Louis Vuitton’s watch division. In addition to the classic collection, with the Tambour, Spin Time and Escale watches, the brand has demonstrated rather impressive expertise in high watchmaking, with its automata and metiers d’art models. But there’s also a strong connection with independent watchmakers, […]

Introducing: The Krayon Anyday – An Incredibly Complicated Movement That Makes Reading The Calendar Extremely Simple (Exclusive & Live Pics)

For all my love of complicated watches with obtuse use-cases, few things could be better than a creative mechanical solution that makes life easier.

Insight: Regulating a Mechanical Watch Movement

A mechanical watch is not always spot on; less-than-perfect timekeeping can happen, often due to an unruly oscillator. The solution is direct adjustments to the hairspring and balance assembly, either slowing down or speeding up the oscillator, a practice known as regulation. Watchmakers have devised multiple innovations to achieve this, including the free-sprung balance, exemplified by the Gyromax of Patek Philippe and Microstella of Rolex. While a simple concept in principle, the mechanics and practice of regulation are nuanced. Here we’ll delve into the theory of regulation and the primary regulating systems: the curb-pin regulator and the free-sprung (or variable inertia) balance. The Lange L043.4 with a screwed balance inspired by pocket watches Basic concepts In order to better understand watch regulation, we need to first cover some of the basic physics behind the watch oscillator: The component responsible for the running rate of a movement is its regulating organ. The regulating organ is made up of a hairspring paired to a balance, which together are also known as a harmonic oscillator. The natural oscillation period is the time it takes the balance to make a full swing, back and forth. The period is made up of two vibrations, one for each direction of the balance motion, with the escapement being unlocked at each vibration. Notably, the natural period of a balance wheel is intrinsic to itself and does not depend on the escapement type or the going train ratio. ...

Introducing: Ming's New Extra-Flat 'Project 21' Revives A Vintage Movement For Its Smallest Watch Yet (Live Pics)

Using a vintage Frédéric Piguet Cal. 21, the brand sizes way down with their new tantalum watch.

Introducing – 35mm, Tantalum, Vintage Piguet Movement… The MING 21.01 “Project 21” Strikes Hard

Watches, like most products from industrial activities, are ruled by constraints and compromises – whether these are commercial, technological, design-oriented or economical. This is why we, watch enthusiasts, can often be rather disappointed by many new releases. Surely, independent watchmakers playing in a much higher price range can overpass some of these constraints, as a […]

Ming’s Latest Release Presents An Updated Look To The Frederic Piguet Caliber 21

Dr. Martens vs. Blundstone: Who is the Chelsea Boot Champion?

Author A.A. Milne wrote in Winnie the Pooh, “When you see someone putting on his big boots, you can be pretty sure that an adventure is going to happen.” I’m of the opinion that one should always be prepared for a little adventure, and thereby a believer in a good pair of boots, just in case.  I can definitively say that shoes are not one of my many vices. If I’m leaving the house, there are two options I will wear 90% of the time: white Nike Air Force Ones, or a pair of leather Chelsea boots. I opt for the latter during the seven-month-long snow season we get in Colorado. Chelsea boots have been my staple since I can remember, as they’re versatile and easy to slip on as I’m running out the door. When I find something I like, I stick with it, only replacing something when necessary and never straying too far from what I know. It was a big deal then, when I swapped my Embury Leather Casual Dr. Martens Chelsea boots for a pair of Blundstone Classic 587s last March.  Dr. Martens were my brand of choice for six years. The same pair of Chelsea boots guided me through the streets of Paris in 2018 and a solo trip to Ireland four years later. My Blundstones are coming up on their first birthday this March, and have traipsed through dirt and debris along Route 66 as well as seven states and a handful of National Parks. Both brands have a lot to offer in terms of heritage, specs, and fit, and both deserve consideration in one’s quest for the perfect Chelsea boot. Bra...

Rolex Cosmograph Daytona vs. Zenith Chronomaster Sport: Head-to-Head

Day One for the Zenith Chronomaster Sport was January 21, 2021. And it seemed like everyone had the same reaction: “That is one aggressive Rolex tribute.” Tim Mosso thinks that the Chronomaster Sport is a distinctive product with its own identity and takes a look here at how it stacks up against the ever-popular Rolex Cosmograph Daytona.
